Subtracting a negative number has the same effect as adding a positive number - think of it as moving right on a number line whereas, subtracting a positive number will move you left on a number line.
The result of subtracting a negative number minus a negative number can be positive, or negative, depending on which of the numbers is larger. It can even be zero.
Depends. If you are subtracting a bigger number from a smaller number, such as 3 - 5, you will get a negative result, -2. If you are subtracting a smaller number from a bigger number, such as 12 - 3 you will get a positive result, 9.
For negatives, two negatives equal a positive & all goes for positive
